The plate 5 carries, pivotally mount- 6o edV upon its face, two bell-crank members 9 and 10 -which constitute what may be designated as a collapsible bracket or table and' a rock lever 20. The upper portion of the upwardly extending arms of the bell-crank o5 members, shaped as shown, are bent over toV lprovide the 'horizontal bracket arms 11 and 12, which extend forwardly past and outside of the posts of the stack. Ihe lower horizontalarms of these two members terminate in vreversed 4or complementary cyma curved P ends the convex arcs 13 and 14 of which overlap and act as lgear teeth. The convex arc 13 of the member 9 Aalso serves in connection with the concave arc of the member 1() asa 75 stop to. limit the movement of the bracket the ends of a razorblade 15 (see Fig. 3) de '80 l osited thereon bythe machine; and these racket arms `are normally and yieldingly held in such operativeposition by a spring 16, which is housed in a cylindrical chamber 17 in the plate andis attached at one end to 85 the plate at the inner end of the chamber and at the other end to a lu 18 at the blick of the memb r 9. The rock ever 20 and the bracket mem r 10 are operatively connected by a pawl 21 pivotally mounted at the back -90 of the former and a pm 22 fixed in the latter above its fulcrum. The toothed end ofthe Y pawl is ieldingly held by a spring 23 in position guide over and engage, the pinv on the inward swing of the rock lever and is bey tripped out of engagement therewith when itstail strikes the stop 24 as the rock lever reaches the limit of its outward movement.

,Thus,v the outward swing of therock lever, the members 9 and 10 will frstbe roclied 100 apart, .to spread the bracket arms to release 'ended cylindrical chamber 25, of reducedVIA size at its inner end, with its axis substantially at-the intersection of, planes passing current supply.

mounted upon plate, and

through the posts of the stack and the two bracket arms respectively, and when the rock lever is swung inwardly, toward the stack, the inner end of the head passes into an opening cut out for the purpose in the adjacent bracket arm` 12. This head carries the contacts of the control switch. The iixed switch contact 26 is yieldingly sup orted adjacent the outer end of the cham er 25 by a spring 27,.of phosphorbronze or other suitable conducting material, which is a rearward extensionat the outer side of the head, suitably insulated therefrom, and is enclosed by a removable cap 28; and this contact is electrically connected with the circuit wire 29,.which as here shown leads from a source of current supply through the coil of the actuating magnet of a number registering device 3l() and is clamped to the back of the extension and then carried through an opening therein and soldered to the rear end ofthe spring 27. The movable.contact 31 is carried at the end of a plunger 32, which is mounted to slide to a limited extent within bearings provided by the reduced inner end of the chamber in the head and a bushing 33 of insulating-material.set into its larger outer end, and is normally held in open position, out of contact with the fixed contact, by a' coil spring 34 plunger inwardly and holds an annular collar 35 thereonseated against the shoulder in the chamber. This contact may be grounded aslshown through the supporting lthe frame ofthe machine, or-it may if desired be connected directly back by wireto the other side ofthe source of The rock lever 20 is here actuated bythe rod 36 of the honing machine, which rod during each operative cycle of the machine moves forward after the edges of a blade have been honed on one side `to turn the blade over and then is immediately withdrawn. The necessary connection; is provided, as shown, by an arm 37 which is clamped to the rod and at its outer end is pivoted to a` block 38 secured, between two adjusting nuts, on the rear end of a connecti-ng rod 39 which rod in turn is pivoted at its forwar end to the long narm of a bell-crank lever l40 fulcrumedV upon a` pin 41 fixed inthe upper edge of the plate 5, the slotted short arm of the lever being operatively connected with the head ofthe rock lever 20 by means of a ball 42 sliding in the ooved sides of the slot and turning vand I sliding axially upon a pin 43 fixed on #the head.

' The-operationof the as above described, is as 36, as stated, reciprocates durin machine-that is to say,

switch, constructed follows: The'rod forward and back during the lnish- Vthe bracket arms 11 which yieldingly presses the each 'operative' cycle of the honingv nevaoso rocks the head of the rock lever 2() from the limit of its inward to the limit of its outward movement and back again. Thus, after a razor blade has been honed, onone side and as it is being turned over preparatory to the honing of its other side, the rock lever 20 is swung inwardly into opera.- tive engagement 10, and there is at once swung back, or outwardly, and by such movement rocks the bracket members, to spread their arms, and then releases them, allowing them to spring back to operative position. This ,action is repeated with each operation of the machine. It is obvious, however, that the switch will not be actuated by the movement of the rock lever if there is no razor blade in place upon and 12 to engage and arrest the movement of the plunger 32, on the inward swing of the head, and so effect the closing of the switch contacts. Hence,

when a machine is started up there will beeach blade being counted while the lnext succeeding blade is being finished, and neither switch nor counter will be actuated by the running of the machine so long as with the bracket member l it is not in productive oper-ation and deliverl ing. blades to the stack.

In theV modification illustrated in Figs. 5 and 6, the switch contacts are omitted and the numbering'device 30 is mounted upon,

or within, the rock lever 20 and is actuated Y directly by the plunger 32. The rock-lever is here hollowed out to provide a chamber 45, for the counter, with window 46 through which the figures-of the counter can be read and a removable front plunger 32 reciprocates within the chamber ,105' cover plate 47. The A 25 in the head of therrock-lever, being held from turning by a pin 48 which projects into akey-way 49 and also serves by engage-ment with the end of the key-way to hold the plunger within the head andto limit its forward movement therein. yThe reduced rear end of the plunger passes through an opening 50 in the rear wall of the chamber 25' and its outer end, within the chamber 45, is

bent about at right angles to provide an arm 51 l which operatively engages the actuating lever arm 52 of the counter, a spring 53 serving to hold the arm of the counter in contact with the arm 51 and-.t0 return the plunger to its extremeforward position within the head when'moved therefrom. -The operation is substantially as in it being obvious vthat on the. forward or inward vswing ofthe rock-lever the plunger willbe reciprocated to actuate the counter only when there is a razor blade heldin the ptatlli1t of its movement on the -posts of the the form first describe-d,` I

It is to be understood that the mechanism described constitutes the unit ot a-system, bein intended for use with each of any num er ot machines whose production is to be measured; and, further, that in the form comprising an electric switch is equally adapted for the control of the circuits of apparatus for registering and/or recording the efiicient operating andthe idle and inefficient operating tlme of a machine as for control- .ling the ac tuatingcircuit of a numbering device as here illustrated, the counters or otherregisters or recorders of the machines being located and grouped together where and as desired. It is also to be understood that the mechanism may be variously modified in its several details and,l with or without such modification, may be used in the measurement of the production of many machines other than honing machines.
